About us

Built by Workers, for Workers

We're not some fancy tech company in Silicon Valley. We're the blokes who got fed up with sweating through another brutal British summer and decided to do something about it.

How Deelzo Started (The Real Story)

July 2022. Manchester. 40°C in the shade – except there was no bloody shade on the construction site where our founder, Mark, was working as a project manager.

By 2PM, half the crew were feeling dizzy. One lad nearly collapsed mixing concrete. That's when Mark thought: "There's got to be a better way than just 'toughing it out.'"

He looked at what was available – those flimsy £10 fans that broke after a week, or those useless "air coolers" that just made the humidity worse. Everything was either built for offices or wouldn't last five minutes on a proper jobsite.

"I spent three years and way too much money developing something that actually works in our conditions. Not for Instagram influencers or office workers – for the grafters who keep this country running." - Mark Thompson, Founder & Former Site Manager

Why We Do What We Do

🏗️

For the Grafters

We know what it's like to be up a scaffold at midday in July, sweating through your hi-vis, wondering if you'll make it to tea break. You shouldn't have to choose between earning a living and staying safe in the heat.

🇬🇧

Built for Britain

Our humidity is different. Our weather's unpredictable. Our workers are tough as nails but deserve gear that works as hard as they do. We designed Deelzo specifically for British conditions – not just copied something from Arizona.

No BS, Just Results

We don't do fancy marketing speak or gimmicks. If it works, we'll tell you. If it doesn't, we won't sell it. Simple as that. Our 60-day guarantee isn't marketing fluff – it's because we're confident this kit actually works.

How We Know It Actually Works

We didn't just build this in a lab and hope for the best. Deelzo Pro was tested by real workers, in real conditions, during some of the hottest days Britain's ever seen.

200+ Hours of real-world testing
15 Different trades tested it
35°C+ Maximum temperature tested
3 Years of development

From road crews in Birmingham to roofers in Brighton, scaffolders in Scotland to delivery drivers in London – if you work outdoors in Britain, someone like you has already put Deelzo through its paces.

The Team Behind Deelzo

We're not a massive corporation with shareholders breathing down our necks. We're a small team of people who've actually worked in the heat and know what it's like.

Mark Thompson

Founder & Product Development

15 years managing construction projects across the UK. Got tired of watching good workers suffer in the heat and decided to fix it. Still puts his hi-vis on to test every product himself.

Sarah Mitchell

Engineering & Design

Former aerospace engineer who switched to designing gear that actually matters to working people. If it can survive her durability tests, it can survive anything a jobsite throws at it.

Dave Reynolds

Customer Support & Testing

20-year veteran delivery driver who knows every trick in the book for staying cool on the road. If you email us with a problem, you're talking to someone who's been there.

What We Stand For

🛠️ Built to Last

Cheap tools are expensive tools. We'd rather you buy one Deelzo that lasts five summers than five cheap fans that break every year. Quality costs more upfront but saves you money long-term.

🤝 Straight Talking

No corporate waffle, no fancy jargon. We tell you exactly what our product does, how it works, and why we think you'll benefit. If you don't like it after 60 days, send it back. No questions asked.

👷 Workers First

Every decision we make starts with one question: "Will this actually help someone doing a hard day's graft?" If the answer's no, we don't do it. That's why our fan clips to hi-vis, charges via USB-C, and runs for 12+ hours.

Join the Cooling Crew

When you buy Deelzo, you're not just getting a fan – you're joining a community of workers who've decided they don't have to suffer through another brutal summer.
